Contextualização do ensino de química a partir do tema dos cigarros eletrônicos: uma sequência didática

Abstract

This study presents a proposal for contextualizing Chemistry teaching through the theme of electronic cigarettes by developing a didactic sequence for high school education. The research is based on the understanding that connecting scientific knowledge to everyday situations supports learning and contributes to a more critical education. Considering the recurrent difficulties in understanding chemical concepts when they are taught in a decontextualized manner, a socially relevant theme is adopted as a strategy to bring school content closer to students' realities. Electronic smoking devices are addressed as a generative theme because of their presence among young people and their association with various chemical substances. The study discusses contextualized teaching, the importance of students' prior knowledge, and the didactic sequence as a way of organizing pedagogical work. Historical, structural, and functional aspects of these devices are presented, as well as the chemical composition of the liquids used. This is a qualitative, bibliographic study aimed at systematizing information and developing a teaching proposal that relates chemical content, especially Organic Chemistry, to the substances found in electronic cigarettes. The resulting sequence is intended as supporting material for Chemistry teaching.
